UNITED STE WINDOW-CLEANING DEVICE.

Application filed. March 28, 1923.

To all whom it may concern:

Be it known that I. FRANK MILLER, a citizen of Poland, residingat West Hoboken, county of Hudson, and State of New Jersey,

have invented certain new and useful Improvements in IVindow-Cleaning Devices, of which the following is a specification.

The present invention relates to improvementsin window cleaning devices, and it is the principal object of my invention to provide a device of a simple and inexpensive construction, which can be readily used on a window to wash and wipe the same.

Another object of my invention is the pro-vision of exchangeable handles for my novel window cleaning device which permit a use of the device with windows of varying heights.

These and other objects of my invention will become more fully known as the description thereof proceeds, and will then be more specifically pointed out in the appended claim.

In the accompanying drawing:

Figure 1 is a front elevation of a window cleaning device constructed according to the present invention.

Figure 2 is a side elevation thereof.

Figure 3 is an end view of a brush.

Figure 4: is a front elevation of a brush, and

Figure 5 is a side view of a modified form of handle.

My device comprises a frame including two side bars 10 and 11 of a form best illustrated in Figure 2 connected in their middle by means of angular bars 12 and 13, having their foot parts 14, 15, and 16, 17 secured to the oppositely disposed inner edges of bars 10 and 11 by means of suitable fastening means, as for instance bolts 18, 18 or the like. The central parts of bars 12 and 13 are shaped to form a socket 19 provided with inner thread for the reception of the threaded end pin 20 of a handle 21.

The lower ends of bars 10 and 11 are undercut to form gripping members 22 and 23 adapted to guide between them a flat piece of rubber wiper 24 inserted into the recess formed by undercutting the ends of the bars, while screws 25 passing through the lower cross bar of the frame and the rubber wiper 24 hold the rubber in place.

Serial No. 628,240.

recess 27 of a bar 10 by means of a locking pawl pivoted at its lower end as at 36 on bar 10, while its upper end is recessed to form shoulders 37 and 38 between which the end of rod 27 is firmly gripped and held in place.

If the use of a long handle is desirable, a

handle 39 as shown in Figure 5 is preferably used, the upper angularly bent end of which is threaded as at 40 and adapted to be engaged in socket 19.

The device operates as follows:

After the brush has been suitably secured on rod 27 by means of collars 29, 30 and nuts 31 and 32, rod 27 is placed with one end into the hole in bar 11, while its other end is placed into the recess 26 of bar 10 and securely clamped into; place by means of clamp pawl 35. According to the size of the window to be cleaned handle 21 or handle 39 are attached to bars 12, 13 by the engagement of their threaded pins 20 and 40 respectively with socket 19.

Vhen now the brush is wetted and the frame is guided over awindow either longitudinally or late-rally, the same will be washed and can then be wiped by means of an obvious manipulation of the wiper 24;.

Having thus described my invention, what I claim is:

In a window cleaning device, a frame comprising side bars connected at one end by across bar and free of connection at the opposite end, the cross bar being formed with a longitudinal slot for the reception of a wiping element, a wiper held therein and a brace strip connecting the side bars intermediate their ends and centrally formed for the reception of a handle.

In testimony whereof I have affixed my signature.

FRANK MILLER.
